For 2 class ,we get 2 x 2 confusion matrix.

Confusion matrix with labels. 2D Semantic Labeling Those measures are computed twice (for full_reference and no_boundaries ). The confusion matrices are defined in a way that in row direction the reference is given, while in column direction the prediction. The cells are then normalised with respect to the reference. This means that rows add up to 100% (round-off errors might occur). Create confusion matrix chart for classification problem confusionchart(trueLabels,predictedLabels) creates a confusion matrix chart from true labels trueLabels and predicted labels predictedLabels and returns a ConfusionMatrixChart object.The rows of the confusion matrix correspond to the true class and the columns correspond to the predicted class.

Subscribe to RSS machine learning - Interpreting confusion matrix and ... Looking at the confusion matrix it is noticeable that the classes 0, 2, 3, 7, 10, 11, 13 and 14 are never predicted. These classes have also the smallest number of samples. I wonder why this happens? Those classes are more rare than the others but nver predicting them seems odd. What would you recommend going forward?
